简介:惯性导航加速度计是惯导系统的关键元件之一,由于单轴摆式加速度计具有量程大、精度高而被广泛使用。对悬丝作为敏感线圈的支撑,在整个单轴摆武加速度计中属关键零件,同时也是加速度计中最易失效的零件。对悬丝断口、材质、工艺过程及测试环境进行了分析研究。结果表明:过载断裂是悬丝的主要失效形式,其次为疲劳断裂;悬丝失效受综合因素的影响,包括悬丝内部缺陷、材质不均、焊接过程控制问题、测试环境因素等,其中最主要的因素是悬丝内部各种缺陷。在此基础上,提出了严格控制悬丝加工工艺过程、改用可焊接性能良好的抗氧化无铅焊料KYHFSn96.5AgCu代替普通的铅锡焊料HLSn40PbA焊接等改进措施,有效地预防了加速度计悬丝的断裂失效。
